LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent N0. 499,944, dated June 20,1893. Application filed February 27 1893. Serial No. 463,808. (No model.)

.shown in Fig. 1, to more fully illustrate said improvements. Fig. 3 is atransverse section on line a Fig. 2, and Figs. 4 and 5 are similar views to Figs. 2 and 3, showing a modification in the construction which Will be hereinafter described.

My invention relates more especially to narrow-ware looms, and consists in combining a spring-friction device with the shuttle, for holding and guiding the filling-thread in its passage from the usual guide-opening or eye in the end of the shuttle to the quill or bobbin thereof, as and for the purpose hereinafter more fully set forth.

In order that others may better understand the nature and purpose of my said invention,

1 will now proceed to describe it more in detail.

In the drawings,A represents the shuttleframe. B the quill or bobbin, which is supported on the removable spindle O, and D a spring friction-pad which bears with a slight pressure on the surface of the thread on said quill or bobbin, as usual.

The above parts are all old, and I make no claim thereto, except in combination with my improvement, which, as before stated, consists of a spring-friction device E for holding and guiding the filling-thread F, in its passage from the usual guide-opening oreye, G, to the quill 0r bobbin B. Said friction device E is arranged inside of the shuttle-frame, between the guide-eye G and the quill or bobbin, and is constructed as follows:A frame or support b is fastened to the shuttleframe A, and to said frame I) is in turn secured at the ends, a guide-rod 0, over which is fitted a spiral-coil cl, adapted to. travel back and forth on said guide-rod. Said coil is adapted to receive the filling thread, F, between the helices thereof, as is shown in the drawings, to hold the same with sufficient lateral pressure to hold the thread taut as it is removed from the quill or bobbin. To facilitate the drawing-01f process, said guiderod 0 is preferably made in a curvedor segment form, so as to bring the helices of the coil as nearly as possible in the line of draft of the thread, as is shown in the first three figures of the drawings, but I do not limit myself thereto, as a straight tube or rod, 0' as shown in Figs. 4 and 5, may be used to accomplish the same result.

In the first three figures the guide-rod c is attached to a segment-shaped disk for support, while in Figs l and 5 a skeleton frame is'shown in lieu of said segment-disk, and a tube in place of the solid guide-rod shown in the other figures. Still other similar constructions might be shown and adopted in practice, and I therefore do not limit myself to any special construction in carrying out the principle of my invention.

It is obvious that by the use of a friction device between the guide-eye G and the quill or bobbin B, the thread is always kept taut as it is drawn from said bobbin, while at the same time not in the least retarding said operation. The device is of special advantage when glazed thread or yarn is used that unwinds readily and is liable to fiy about if not held taut.

By the use of a spiral-coil the thread or yarn is easily threaded by simply drawing it down between its helices at any point in its length and said coil automatically adapts itself to the line of draft from the quill.

Having now described my invention, what I claim therein as new, and desire to secure by Letters Patent, is

In a loom-shuttle, the combination of the shuttle-frame and quill or bobbin with a 5 thread friction device, arranged between the guide-eye of said shuttle and said quill or bobbin, and consisting of a spiral coil fitted to slide longitudinally on a suitable support, substantially as and for the purpose set forth.
